Union Auction

What Union Auction does

Union Auction Public Company Limited, trading as AUCT on the Stock Exchange of Thailand's mai market under ticker AUCT, operates Thailand's largest vehicle auction platform. The firmographics record indicates founding in 1991, while a separate historical source dates establishment to 2014 as Thailand's first organized car auction yard; the company has since auctioned over 1 million items cumulatively. Headquartered in Bangkok's Wang Thonglang district with 101-250 employees, the company runs a multi-channel auction business spanning on-site auction yards at 14+ branches across Thailand, a real-time online bidding platform (AUCTLive), a 24-hour auction format (AUCT Bid), and proxy bidding. Beyond vehicles, the AUCTBID sub-brand auctions real estate, while AUCT Place represents the physical branch network. Supporting sub-brands include GO AUCT (consignment sales) and AUCT Finn (vehicle financing and refinancing), and ancillary services include standardized car and motorcycle grading, insurance (compulsory and voluntary), logistics and transportation, registration document handling, and an AUCT Garage workshop.

The business model is fundamentally transaction-fee-driven: sellers list vehicles and pay listing/commission fees while buyers pay buyer premiums on winning bids, with revenue supplemented by professional services fees from grading, inspection, logistics, insurance, and credit/financing activities. Pricing is variable and auction-based with no standardized public tiers, consistent with pay-as-you-go transaction economics. The platform combines a primarily consumer-facing sales-led GTM (multiple participation channels: in-person, online, proxy, 24-hour) with an event-driven model anchored by regular themed auction sessions such as the monthly Bid Big Bike auctions. Customers span individual buyers and sellers, car dealerships sourcing inventory, financial institutions disposing of repossessed or fleet vehicles, corporate fleet owners, and property investors via AUCTBID. Key institutional partners include Krungsri Bank, Honda Leasing (Thailand), Kiatnakin Phatra (KKP), National Credit Bureau, Car Credo Japan (Goo Inspection), and the Used Car Dealers Association of Thailand. The company is ranked in the top 10 of the SET's mai market and maintains investor relations through a dedicated IR portal.

Expansion highlights6 records

Emerging players

• Carsome: Southeast Asia's largest used car marketplace, offering inspection, financing, and direct purchase of used vehicles. Competes with Union Auction for dealer and consumer vehicle sourcing, though operates a digital-first model rather than physical auction yards.
• Carro: Singapore-headquartered used car marketplace and fintech platform operating across Southeast Asia. Competes in the same regional used vehicle transaction space as Union Auction, with a digital-native model and embedded financing.

Broad incumbents

• Copart: Global leader in online vehicle auctions and remarketing with a similar model of physical yards combined with online bidding. Comparable business model and core auction platform, though operating at much larger scale and primarily in the US/Europe.
• Manheim (Cox Automotive): Largest US wholesale vehicle auction operator, offering physical and online auctions plus adjacent services like financing, inspection, and transportation — directly analogous to Union Auction's integrated vehicle auction ecosystem.
• KAR Auction Services (ADESA): North American wholesale vehicle auction operator with digital and physical auction platforms serving dealers, fleets, and OEMs. Comparable integrated auction services and technology stack, though significantly larger and more diversified.
• RB Global (IAA): Global auction platform for vehicles and industrial assets, including salvage and used vehicle auctions. Comparable online-plus-physical auction model, though primarily serving North American and European markets.

Direct peers

• USS Co., Ltd. Japan's largest used vehicle auction operator with a hybrid online and onsite auction model serving dealers. Closest structural comparator to Union Auction given the Asian market dynamics, dealer-focused B2B auctions, and diversified automotive services.
• BCA Marketplace: UK-based wholesale vehicle auction operator with online and physical auction infrastructure serving fleet operators and dealers. Directly comparable business model in vehicle remarketing, though focused on the European market.
• Aucnet Inc. Japan-headquartered B2B auction house specializing in used vehicles, motorcycles, and other assets via online real-time bidding. Highly comparable business model to Union Auction's AUCTLive platform and multi-category auction ambition.

Others

• Honda Auto Terrace: OEM-affiliated used vehicle sales network in Japan. While not a direct auction peer, it represents the OEM-channel source of used vehicle supply that flows into Union Auction's auction platform, especially for Honda Leasing (Thailand) volume.
